fatty acids
The cell membrane or cell wall.

Part of the cell is mostly water and minerals called the cell membrane
The cell membrane is made out of two layers , a nonpolar and polar part. The polar part is the hydrophilic part , meaning water loving , and the nonpolar is hydrophobic part - water hating. The polar/hydrophilic part is inside of the membrane and the outer portion is the hydrophobic/nonpolar . You don't want the cell to exist in water or be soluble in water because then we would dissolve , all our cells , tissues etc. That's why the cell membranes outer portion is nonpolar and is not miscible with water . The cell membrane allows water molecules to come in and out of the cell by osmosis , and that is when water molecules can free out and in of the cell through the cell membrane .

it occurs in the cell membrane(through the cell membrane really)

The Cell membrane, along with its integrated proteins. In prokaryotes the Cell membrane is bolstered by the [mostly cellulosic] Cell Wall; in eukaryotes the Cell membrane is bolstered by the [glyco-protein] Cell Coat.
